　意匠部３０は、操作スイッチ４を覆うように配置される樹脂製の操作ハンドル部１と、操作ハンドル部１の周囲を囲うカバー２とを備える。操作ハンドル部１は、使用者が換気扇４２のオンオフの切替及び運転強度の強弱を切り替えるための部品であり、スイッチ１００の前面に設置されている。カバー２は、取付枠３に対して爪などによる嵌合で取り付けられる。 The design section 30 includes an operating handle section 1 made of resin and arranged to cover the operating switch 4, and a cover 2 surrounding the operating handle section 1. The operation handle part 1 is a part that allows the user to turn on and off the ventilation fan 42 and to change the intensity of operation, and is installed on the front surface of the switch 100. The cover 2 is attached to the attachment frame 3 by fitting with claws or the like.

The second operation handle 52 is a component for switching the operating intensity of the ventilation fan 42 by user operation. The display unit 53 displays the on/off state of the ventilation fan 42, the operating intensity state, and the wireless communication state.
　器体２０は、制御部５、通信部６、保護カバー７及び電源部８を備える。また、器体２０は、制御部５、通信部６、保護カバー７及び電源部８を収納する四角筒状の器体カバー９と、器体カバー９の前面を覆う操作スイッチ４とを備える。操作スイッチ４には、操作ハンドル部１が爪などによる嵌合で取り付けられる。なお、器体カバー９は、筒状であればよく、四角筒状に限定されない。 The container body 20 includes a control section 5, a communication section 6, a protective cover 7, and a power supply section 8. Further, the container body 20 includes a rectangular cylindrical container cover 9 that houses the control section 5, the communication section 6, the protective cover 7, and the power supply section 8, and an operation switch 4 that covers the front surface of the container cover 9. The operating handle portion 1 is attached to the operating switch 4 by fitting with a claw or the like. Note that the vessel cover 9 only needs to have a cylindrical shape, and is not limited to a square cylindrical shape.
　操作スイッチ４には、スイッチ伝動部４ａが設けられている。スイッチ伝動部４ａは変形可能であり、第１操作ハンドル５１又は第２操作ハンドル５２が押下されると制御部５側へ変形する。スイッチ伝動部４ａが制御部５側へ変形すると、制御部５に設けられた不図示のボタンが押下される。 The operation switch 4 is provided with a switch transmission part 4a. The switch transmission part 4a is deformable, and deforms toward the control part 5 when the first operating handle 51 or the second operating handle 52 is pressed down. When the switch transmission section 4a is deformed toward the control section 5, a button (not shown) provided on the control section 5 is pressed.
　制御部５は、電源部８に対して、出力状態を指示する出力指令信号を出力する。出力状態は、強運転、弱運転及び停止の三つの状態である。制御部５は、操作ハンドル部１に対する換気扇４２の運転状態の切り替えを要求する操作に基づいて出力指令信号を生成する。 The control unit 5 outputs an output command signal to the power supply unit 8 to instruct the output state. There are three output states: strong operation, weak operation, and stop. The control unit 5 generates an output command signal based on an operation performed on the operating handle unit 1 to request switching of the operating state of the ventilation fan 42 .
　制御部５は、通信部６に対して通信配線６０を介して通信用信号を出力する。通信用信号は、状態変化信号として出力される。すなわち、運転状態がオンからオフに切り替わったことを示す第１状態変化信号、運転状態がオフからオンに切り替わったことを示す第２状態変化信号、運転強度が強から弱に切り替わったことを示す第３状態変化信号、運転強度が弱から強に切り替わったことを示す第４状態変化信号を定めておき、操作ハンドル部１に対する操作により状態が切り替わったときに、それぞれに対応する状態変化信号を出力する。 The control unit 5 outputs a communication signal to the communication unit 6 via the communication wiring 60. The communication signal is output as a state change signal. That is, a first state change signal indicates that the operating state has switched from on to off, a second state change signal indicates that the operating state has switched from off to on, and a second state change signal indicates that the operating intensity has switched from strong to weak. A third state change signal and a fourth state change signal indicating that the driving intensity has switched from weak to strong are defined, and when the state is switched by operating the operating handle part 1, the corresponding state change signals are transmitted. Output.
　通信部６は、器体カバー９のうち、保護カバー７が配置された部分よりも前方の部分に収納されている。通信部６は、制御部５から通信配線６０を介して出力された状態変化信号を受けて、無線信号６５をルータ６１に対して出力する。 The communication unit 6 is housed in a portion of the container cover 9 that is forward of the portion where the protective cover 7 is placed. The communication unit 6 receives the state change signal output from the control unit 5 via the communication wiring 60 and outputs a wireless signal 65 to the router 61 .
　通信部６は、状態変化信号を制御部５から受信し、状態変化信号が示す運転状態及び運転強度を無線信号にてユーザ端末６４へ送信する。また、操作ハンドル部１以外での切替操作、例えばユーザ端末６４による遠隔操作の信号を受信し、電源部８へ信号を送信する。通信部６が遠隔操作の信号を電源部８に送信することで、電源部８内のリレーを開閉させることができる。 The communication unit 6 receives the state change signal from the control unit 5, and transmits the driving state and driving intensity indicated by the state change signal to the user terminal 64 as a wireless signal. It also receives a signal from a switching operation other than the operation handle section 1, for example, a remote operation from the user terminal 64, and transmits the signal to the power supply section 8. When the communication unit 6 transmits a remote control signal to the power supply unit 8, a relay in the power supply unit 8 can be opened or closed.
　電源部８は、電子回路の開閉を行う電子部品の他に、外部電源８６を換気扇４２などの負荷が接続される端子台２１を持つ。電源部８は、端子台２１を通じて電源が供給されるとともに、負荷側へ電源を供給する。 The power supply unit 8 has a terminal block 21 to which an external power supply 86 and a load such as a ventilation fan 42 are connected, in addition to electronic components that open and close electronic circuits. The power supply section 8 is supplied with power through the terminal block 21 and also supplies power to the load side.
　端子台２１は、外部電源８６から交流１００Ｖの電力供給を受ける電源入力線８１が接続される電源入力端子８２と、モータ回路４１に直流電力を供給する出力配線４０が接続される出力端子８３とを備えている。電源部８は、外部電源８６から供給される１００Ｖの交流から１２Ｖの直流を生成し、制御配線５０を通じて制御部５に供給する。通信部６には、制御部５から通信配線６０を通じて１２Ｖの直流が供給される。したがって、制御部５及び通信部６には、外部電源８６から電源部８に供給される電圧よりも低い電圧が印加される。また、電源部８は、制御部５からの出力指令信号に基づいて、モータ回路４１に負荷駆動電力を供給する。 The terminal block 21 has a power input terminal 82 to which a power input line 81 that receives 100V AC power from an external power supply 86 is connected, and an output terminal 83 to which an output wiring 40 that supplies DC power to the motor circuit 41 is connected. It is equipped with Power supply unit 8 generates 12V DC from 100V AC supplied from external power supply 86 and supplies it to control unit 5 through control wiring 50 . The communication unit 6 is supplied with 12V DC from the control unit 5 through the communication wiring 60 . Therefore, a voltage lower than the voltage supplied from the external power supply 86 to the power supply section 8 is applied to the control section 5 and the communication section 6. Further, the power supply section 8 supplies load driving power to the motor circuit 41 based on the output command signal from the control section 5 .
　保護カバー７は、電源部８よりも前方に配置されて器体カバー９の内壁と当接し、器体カバー９内の電源部８が配置された空間を操作ハンドル部１から隔離する。例えば、保護カバー７は、電源部８と通信部６との間に配置される。実施の形態１では、電源部８は５０Ｖ以上の高い電圧が印加される高電圧部であり、制御部５及び通信部６は５０Ｖ未満の低い電圧が印加される低電圧部である。保護カバー７は、高電圧部である電源部８での発熱が低電圧部である制御部５及び通信部６と、操作部である操作ハンドル部１とへ影響することを抑制する。 The protective cover 7 is disposed in front of the power supply section 8 and comes into contact with the inner wall of the container cover 9, and isolates the space in the container cover 9 in which the power supply section 8 is arranged from the operation handle section 1. For example, the protective cover 7 is placed between the power supply section 8 and the communication section 6. In the first embodiment, the power supply section 8 is a high voltage section to which a high voltage of 50V or more is applied, and the control section 5 and the communication section 6 are low voltage sections to which a low voltage of less than 50V is applied. The protective cover 7 suppresses heat generation in the power supply section 8, which is a high voltage section, from affecting the control section 5 and communication section 6, which are low voltage sections, and the operation handle section 1, which is an operation section.
　配線ボックス１０は、器体２０を覆うように配置される。スイッチ１００は、端子台２１に接続される配線が配線ボックス１０に収納された状態で、取付穴３ａを通したネジによって壁１１０に固定される。 The wiring box 10 is arranged to cover the container body 20. The switch 100 is fixed to the wall 110 with screws passed through the mounting holes 3a, with the wiring connected to the terminal block 21 housed in the wiring box 10.
　図８は、実施の形態１に係るスイッチの電源部の概略構成を示す図である。なお、電源部８の詳細な構造については後述する。制御部５は、不図示のリード線及びコネクタを用いて通信部６及び電源部８と電気的に接続されている。制御部５の第１操作ハンドル５１が押下されることで電源部８内の第１リレー９０が閉じられ、換気扇４２に電流が流れる。すなわち、第１操作ハンドル５１は、電源入力線８１を遮断から接続に切り替える切替操作と、電源入力線８１を切断から遮断へ切り替える切替操作を受け付ける。第１リレー９０が閉じられた直後の電流は突入電流と呼ばれ、瞬間的に大きな電流が流れる。特に直流モータ搭載機器では回路の仕様上、交流モータ搭載機器と比較して大きな電流が流れる。この突入電流を低減するために、電源部８は、第２リレー９１及びバイパス抵抗９２を備える。第１リレー９０が閉じられた直後は第２リレー９１が開かれているため、バイパス抵抗９２に電流が流れる。一定時間経過すると第２リレー９１が閉じられることで電子部品に流れる突入電流を低減させることができる。 FIG. 8 is a diagram showing a schematic configuration of the power supply section of the switch according to the first embodiment. Note that the detailed structure of the power supply unit 8 will be described later. The control section 5 is electrically connected to the communication section 6 and the power supply section 8 using lead wires and connectors (not shown). When the first operation handle 51 of the control section 5 is pressed down, the first relay 90 in the power supply section 8 is closed, and current flows through the ventilation fan 42. That is, the first operation handle 51 receives a switching operation for switching the power input line 81 from cutoff to connection, and a switching operation for switching the power input line 81 from cutoff to cutoff. The current immediately after the first relay 90 is closed is called an inrush current, and a large current flows instantaneously. Particularly in equipment equipped with a DC motor, a larger current flows than equipment equipped with an AC motor due to the circuit specifications. In order to reduce this rush current, the power supply unit 8 includes a second relay 91 and a bypass resistor 92. Immediately after the first relay 90 is closed, the second relay 91 is open, so current flows through the bypass resistor 92. After a certain period of time has elapsed, the second relay 91 is closed, thereby reducing the rush current flowing through the electronic components.
　第２リレー９１を閉じる時刻は、制御部５にて任意に設定可能である。すなわち、第２リレー９１を開いている期間は、制御部５にて設定可能である。したがって、突入電流の流れる時間を変更したい場合は、制御部５にて第２リレー９１を閉じる時刻の設定を変更することで容易に対応可能である。 The time to close the second relay 91 can be arbitrarily set by the control unit 5. That is, the period during which the second relay 91 is open can be set by the control unit 5. Therefore, if it is desired to change the time during which the rush current flows, this can be easily done by changing the setting of the time when the second relay 91 is closed in the control section 5.
　スイッチ１００に突入電流が大きい機器を接続したい場合においても、バイパス抵抗９２のみ変更すればよく、第１リレー９０及び第２リレー９１は変更する必要がないため、容易に対応可能である。 Even when it is desired to connect a device with a large inrush current to the switch 100, it is possible to easily handle this because only the bypass resistor 92 needs to be changed, and the first relay 90 and the second relay 91 do not need to be changed.
　図９は、実施の形態１に係るスイッチから負荷駆動電力が供給されるモータ回路の構成を示す図である。図９は、交流誘導機モータを使用する場合のモータ回路４１の例を示している。図９に示すように、モータ回路４１は、交流電源に補助巻線１１１と主巻線１１２とを並列に接続し、補助巻線１１１にコンデンサ１１３を直列接続して構成されたコンデンサ誘導電動機を備えている。補助巻線１１１と主巻線１１２とは、コンデンサ１１３により、位相が９０°ずれている。主巻線１１２には変速巻線１１４が直列に重ね巻きされる。交流電源の接続位置を、片方を共通位置１１６に接続し、もう片方を主巻線１１２のみを含む位置１１７と、主巻線１１２と変速巻線１１４とを含む位置１１８とで切換えることで、コンデンサ誘導電動機における速度調整を行う。 FIG. 9 is a diagram showing the configuration of a motor circuit to which load driving power is supplied from the switch according to the first embodiment. FIG. 9 shows an example of a motor circuit 41 when using an AC induction motor. As shown in FIG. 9, the motor circuit 41 is a capacitor induction motor configured by connecting an auxiliary winding 111 and a main winding 112 in parallel to an AC power source, and connecting a capacitor 113 to the auxiliary winding 111 in series. We are prepared. The auxiliary winding 111 and the main winding 112 are out of phase by 90° due to the capacitor 113. A variable speed winding 114 is wound over the main winding 112 in series. By switching the connection position of the AC power supply between one side connected to the common position 116 and the other side between a position 117 including only the main winding 112 and a position 118 including the main winding 112 and the variable speed winding 114, Perform speed adjustment in a capacitor induction motor.

It includes an output wiring 40b for operation and a common wiring 40c connected to the common position 116. When commanding strong operation, the power supply unit 8 applies 100 V AC power between the output wiring 40a for strong operation and the common wiring 40c, and causes current to flow through the main winding 112 and the auxiliary winding 111, thereby executing the strong operation. do. At the time of the weak operation command, the power supply section 8 applies 100 V AC power between the weak operation output wiring 40b and the common wiring 40c, and causes current to flow through the main winding 112, the auxiliary winding 111, and the variable speed winding 114. Perform gentle operation.

FIG. 10 is a schematic diagram of the power supply section of the switch according to the first embodiment.

　入力部８４は、外部電源８６から交流電力の供給を受けて、一部を直流低電圧電力に変換し、直流低電圧電源出力配線８５を介して制御部５に供給し、一部を負荷電力として出力配線４０からモータ回路４１に出力する。 The input unit 84 receives AC power from an external power supply 86, converts a part of it into DC low voltage power, supplies it to the control unit 5 via a DC low voltage power output wiring 85, and converts a part of it into load power. It is output from the output wiring 40 to the motor circuit 41 as a signal.

When the third signal line 123 is off, the third relay 94 is in an open state, that is, in a cutoff state.
　第１リレー９０及び第２リレー９１の動作について説明する。図１１は、実施の形態１に係るスイッチの信号波形を示す図である。図１１において、第１操作ハンドル５１に対する換気扇４２のオンオフ切替操作による指令状態を「オンオフ信号」に示す。オンオフ信号は、換気扇４２のオンを指示するときはハイレベルであり、換気扇４２のオフを指示するときはローレベルである。時刻Ｔ１で換気扇４２のオンが指示され、時刻Ｔ４で換気扇４２のオフが指示される。 The operations of the first relay 90 and the second relay 91 will be explained. FIG. 11 is a diagram showing signal waveforms of the switch according to the first embodiment. In FIG. 11, an "on/off signal" indicates a command state caused by an on/off switching operation of the ventilation fan 42 with respect to the first operating handle 51. The on/off signal is at a high level when instructing to turn on the ventilation fan 42, and is at a low level when instructing to turn off the ventilation fan 42. At time T1, the ventilation fan 42 is instructed to be turned on, and at time T4, the ventilation fan 42 is instructed to be turned off.
　「オンオフ信号」が制御部５に入力され、第１リレー９０及び第２リレー９１への指令信号が出力される。時刻Ｔ１において換気扇４２のオンが指示されるとき、第２リレー９１は閉状態、すなわち導通状態である。「オンオフ信号」が時刻Ｔ１で換気扇４２のオンを指示するように変化すると、第２リレー信号は時刻Ｔ１から時刻Ｔ３までオフされ、時刻Ｔ３以降はオンに戻る。 The "on/off signal" is input to the control unit 5, and command signals to the first relay 90 and the second relay 91 are output.

When the "on-off signal" changes to instruct to turn on the ventilation fan 42 at time T1, the second relay signal is turned off from time T1 to time T3, and is turned back on after time T3.
　第１リレー９０は、時刻Ｔ１と時刻Ｔ３との間の時刻Ｔ２において閉じられる。すなわち、第１リレー９０は、第２リレー９１が開かれた状態で閉じられる。 The first relay 90 is closed at time T2 between time T1 and time T3. That is, the first relay 90 is closed while the second relay 91 is opened.
　第１リレー９０が閉じられた瞬間は、第２リレー９１は開かれているため、電流はバイパス抵抗９２のみを流れる。第１リレー９０が閉じられた瞬間には突入電流が流れるが、バイパス抵抗９２により電圧が降下するため、モータ回路４１に印加される電圧も降下し、突入電流によるモータ回路４１への影響を低減させることができる。 At the moment when the first relay 90 is closed, the second relay 91 is open, so current flows only through the bypass resistor 92. An inrush current flows at the moment the first relay 90 is closed, but since the voltage drops due to the bypass resistor 92, the voltage applied to the motor circuit 41 also drops, reducing the influence of the inrush current on the motor circuit 41. can be done.
　突入電流収束後の時刻Ｔ３に、第２リレー９１を閉じることで、時刻Ｔ３以降はバイパス抵抗９２による電力消費を回避することができる。 By closing the second relay 91 at time T3 after the inrush current converges, power consumption by the bypass resistor 92 can be avoided after time T3.
　時刻Ｔ２から時刻Ｔ３の間はバイパス抵抗９２を経由して電流を流すが、この際には電流を１／１０程度に抑制する。従って、時刻Ｔ２から時刻Ｔ３の時間は、交流周期の１０倍程度の時間とすれば良い。すなわち、バイパス時間は十ｍｓｅｃオーダーから百ｍｓｅｃオーダーとすれば良い。 Between time T2 and time T3, current flows through the bypass resistor 92, but at this time, the current is suppressed to about 1/10. Therefore, the time from time T2 to time T3 may be about 10 times the AC cycle. That is, the bypass time may be on the order of 10 msec to 100 msec.
　スイッチオフ時も同様である。「オンオフ信号」が時刻Ｔ４で換気扇４２のオフを指示するように変化すると、第２リレー信号は時刻Ｔ４から時刻Ｔ６までオフされ、時刻Ｔ６以降はオンに戻る。 The same applies when the switch is turned off. When the "on-off signal" changes to instruct the ventilation fan 42 to be turned off at time T4, the second relay signal is turned off from time T4 to time T6, and then turned back on after time T6.
　第１リレー９０は、時刻Ｔ４と時刻Ｔ６との間の時刻Ｔ５において開かれる。すなわち、第１リレー９０は、第２リレー９１が開かれた状態で開かれる。 The first relay 90 is opened at time T5 between time T4 and time T6. That is, the first relay 90 is opened while the second relay 91 is opened.
　第１リレー９０が開かれた瞬間は、第２リレー９１が開かれているため、電流はバイパス抵抗９２のみを流れる。第１リレー９０が開かれた瞬間は、スイッチングノイズが発生するが、バイパス抵抗９２により電圧が降下するため、電子回路への影響を低減させることができる。 At the moment when the first relay 90 is opened, the second relay 91 is opened, so the current flows only through the bypass resistor 92. Switching noise occurs at the moment the first relay 90 is opened, but since the voltage drops due to the bypass resistor 92, the influence on the electronic circuit can be reduced.
　図１２は、実施の形態１に係るスイッチから負荷駆動電力が供給されるモータ回路の構成を示す図である。図１２は、直流モータを使用する場合のモータ回路４１の構成を示している。直流モータのモータ回路４１は、検出部２５０と、整流部２１０と、平滑部２２０と、スイッチング部２３０と、モータ巻線部２４０と、を備える。 FIG. 12 is a diagram showing the configuration of a motor circuit to which load driving power is supplied from the switch according to the first embodiment. FIG. 12 shows the configuration of the motor circuit 41 when using a DC motor. The motor circuit 41 of the DC motor includes a detection section 250, a rectification section 210, a smoothing section 220, a switching section 230, and a motor winding section 240.
　検出部２５０は、スイッチ１００からの入力が強端子から入力されたか、弱端子から入力されたかを検出し、スイッチング制御部２３１に出力する。 The detection unit 250 detects whether the input from the switch 100 is input from the strong terminal or the weak terminal, and outputs it to the switching control unit 231.
　整流部２１０は、ダイオードブリッジ回路２１１により、入力電圧の負電圧分を正電圧に変換して全波整流し、交流電力を脈動する直流に変換する。 The rectifier 210 converts the negative voltage component of the input voltage into a positive voltage using a diode bridge circuit 211, performs full-wave rectification, and converts AC power into pulsating DC.
　平滑部２２０は、平滑コンデンサ２２１により脈動電圧を平滑化する。 The smoothing unit 220 smoothes the pulsating voltage using a smoothing capacitor 221.
　スイッチング部２３０は、スイッチング素子を順に切り替えることにより、固定子のモータ巻線部２４０への供給を順に切り替え、モータに対して回転磁界を与える。切り替え制御方法としては、スイッチング制御部２３１にて、例えば回転子を磁石回転子とし、固定子側にホール素子を設けて回転子の回転角度を検出し、回転角度に応じてスイッチング素子を順に切り替える方法がある。また、スイッチング制御部２３１は、強弱のどちらが選択されているかの信号を検出部２５０から受信して、強弱運転を制御する。 The switching unit 230 sequentially switches the supply of the stator to the motor winding unit 240 by sequentially switching the switching elements, thereby applying a rotating magnetic field to the motor. As a switching control method, the switching control unit 231 uses, for example, a magnet rotor as the rotor, a Hall element is provided on the stator side, detects the rotation angle of the rotor, and switches the switching elements in order according to the rotation angle. There is a way. Further, the switching control unit 231 receives a signal from the detection unit 250 indicating which of the strong and weak modes is selected, and controls the strong and weak operation.
　モータ巻線部２４０は、固定子に巻かれており、順に電流を切り替えることにより、回転磁界を形成する。 The motor winding section 240 is wound around the stator, and forms a rotating magnetic field by sequentially switching the current.
　電源オフ時には平滑コンデンサ２２１の電荷は放出されているため、電源投入時にはまず平滑コンデンサ２２１を充電する必要があり、突入電流の原因となる。すなわち、平滑コンデンサ２２１を使用する直流モータでは、突入電流は大きくなる。 Since the charge in the smoothing capacitor 221 is released when the power is turned off, it is necessary to charge the smoothing capacitor 221 first when the power is turned on, which causes an inrush current. That is, in a DC motor using the smoothing capacitor 221, the rush current becomes large.
　実施の形態１に係るスイッチ１００では、入力部８４から制御部５に直流低電圧電力が供給されるが、大きな突入電流が流れると、制御部５側への電源にも変動ノイズが発生する。特に、通信部６は、ノイズの影響を受けやすいが、実施の形態１に係るスイッチ１００により、突入電流を抑制できるため、通信部６へのノイズによる誤動作を抑制することができる。 In the switch 100 according to the first embodiment, DC low voltage power is supplied from the input section 84 to the control section 5, but when a large rush current flows, fluctuation noise is also generated in the power supply to the control section 5 side. In particular, the communication unit 6 is easily affected by noise, but the switch 100 according to the first embodiment can suppress inrush current, so malfunctions caused by noise to the communication unit 6 can be suppressed.
　また、壁面設置型のスイッチの場合、全体のサイズは決められているが、通信機能を使用するために通信部を設けると、スイッチ全体のサイズを維持するために、リレー部の大型化を抑制することが求められる。従来のスイッチでは、１０Ａ未満の定格電流に対しても、突入電流は１０倍程度の電流が流れる。これに対し、実施の形態１に係るスイッチ１００では、突入時にはバイパス抵抗９２を経由するため、電気抵抗が１０Ωから１００Ω程度のバイパス抵抗９２を用いることにより、突入電流を定格電流と同等に抑制することができる。このため、実施の形態１に係るスイッチ１００は、リレー部などの部品サイズをアップさせることなく、オンオフ切替操作時に発生する突入電流を低減できる。 In addition, in the case of a wall-mounted switch, the overall size is determined, but if a communication section is provided to use the communication function, the size of the relay section can be suppressed in order to maintain the overall size of the switch. are required to do so. In conventional switches, even with a rated current of less than 10 A, an inrush current of about 10 times flows. On the other hand, in the switch 100 according to the first embodiment, since the inrush current passes through the bypass resistor 92, the inrush current is suppressed to be equal to the rated current by using the bypass resistor 92 with an electrical resistance of about 10Ω to 100Ω. be able to. Therefore, the switch 100 according to the first embodiment can reduce the rush current generated during the on/off switching operation without increasing the size of components such as the relay section.
実施の形態２．
　実施の形態２に係るスイッチ１００の構成は、実施の形態１に係るスイッチ１００と同様である。図１３は、実施の形態２に係るスイッチの信号波形を示す図である。第２操作ハンドル５２は、電源入力線８１の接続先切替操作を受け付ける。第２操作ハンドル５２に対する操作により電源入力線８１の接続先が切り替えられることにより、換気扇４２の運転強度の強弱が変更される。図１３において、第２操作ハンドル５２の操作による指令状態を「強弱信号」に示す。強弱信号は、換気扇４２に強運転を指示するときはハイレベルであり、換気扇４２に弱運転を指示するときはローレベルである。時刻Ｔ１１で換気扇４２の運転強度を強にする信号が出力され、時刻Ｔ１４で換気扇４２の運転硬度を弱にする信号が出力される。 Embodiment 2.
The configuration of switch 100 according to the second embodiment is the same as that of switch 100 according to the first embodiment. FIG. 13 is a diagram showing signal waveforms of the switch according to the second embodiment. The second operation handle 52 accepts an operation to switch the connection destination of the power input line 81. By operating the second operating handle 52 to switch the connection destination of the power input line 81, the operating intensity of the ventilation fan 42 is changed. In FIG. 13, the command state by operating the second operating handle 52 is shown as "strength/weakness signal". The strength signal is at a high level when instructing the ventilation fan 42 to operate in a strong manner, and is at a low level when instructing the ventilation fan 42 to operate in a weak manner. At time T11, a signal that increases the operating intensity of the ventilation fan 42 is output, and at time T14, a signal that reduces the operating intensity of the ventilation fan 42 is output.
　第２操作ハンドル５２が操作されることにより、「強弱信号」が制御部５に入力され、第２リレー９１及び第３リレー９４への指令信号が出力される。弱信号が出力される状態では、第２リレー９１は閉状態、すなわち導通状態である。強指令により「強弱信号」が時刻Ｔ１１で強になると、第２リレー信号は時刻Ｔ１１から時刻Ｔ１３までオフされ、時刻Ｔ１３以降はオンに戻る。 By operating the second operating handle 52, a "strength signal" is input to the control unit 5, and a command signal to the second relay 91 and third relay 94 is output. In a state where a weak signal is output, the second relay 91 is in a closed state, that is, in a conductive state. When the "strong/weak signal" becomes strong at time T11 due to the strong command, the second relay signal is turned off from time T11 to time T13, and is turned back on after time T13.
　第３リレー９４は、時刻Ｔ１１と時刻Ｔ１３との間の時刻Ｔ１２で閉じられる。すなわち、第３リレー９４は、第２リレー９１が開かれた状態で切り替えられる。 The third relay 94 is closed at time T12 between time T11 and time T13. That is, the third relay 94 is switched while the second relay 91 is open.
　第３リレー９４が閉じられた瞬間は、第２リレー９１が開かれているため、電流はバイパス抵抗９２のみを流れる。第３リレー９４が閉じられて強弱出力配線が切り替わった瞬間には突入電流が流れるが、バイパス抵抗９２により電圧が降下するため、モータ回路４１に印加される電圧も降下し、突入電流によるモータ回路４１への影響を低減させることができる。 At the moment when the third relay 94 is closed, the second relay 91 is open, so current flows only through the bypass resistor 92. An inrush current flows at the moment the third relay 94 is closed and the strong/weak output wiring is switched, but since the voltage drops due to the bypass resistor 92, the voltage applied to the motor circuit 41 also drops, and the motor circuit due to the inrush current 41 can be reduced.
　突入電流収束後の時刻Ｔ１３で、第３リレー９４を閉じることで、時刻Ｔ１３以降はバイパス抵抗９２による電力消費を回避することができる。 By closing the third relay 94 at time T13 after the inrush current converges, power consumption by the bypass resistor 92 can be avoided after time T13.
　弱指令時も同様である。「強弱信号」が時刻Ｔ１４で弱になると、第２リレー信号は時刻Ｔ１４から時刻Ｔ１６までオフされ、時刻Ｔ１６以降はオンに戻る。 The same applies to weak commands. When the "strong/weak signal" becomes weak at time T14, the second relay signal is turned off from time T14 to time T16, and is turned back on after time T16.
　第３リレー９４は、時刻Ｔ１４と時刻Ｔ１６との間の時刻Ｔ１５のタイミングで開かれる。すなわち、第３リレー９４は、第２リレー９１が開かれた状態で切り替えられる。 The third relay 94 is opened at time T15 between time T14 and time T16. That is, the third relay 94 is switched while the second relay 91 is open.
　第３リレー９４が開かれた瞬間は、第２リレー９１が開かれているため、電流はバイパス抵抗９２のみを流れる。第３リレー９４が開かれた瞬間にも、閉じられた瞬間と同様に突入電流が流れるが、バイパス抵抗９２により電圧が降下するため、モータ回路４１に印加される電圧も降下し、突入電流によるモータ回路４１への影響を低減させることができる。 At the moment when the third relay 94 is opened, the second relay 91 is opened, so the current flows only through the bypass resistor 92. At the moment the third relay 94 is opened, an inrush current flows in the same way as at the moment it is closed, but since the voltage drops due to the bypass resistor 92, the voltage applied to the motor circuit 41 also drops, and the inrush current The influence on the motor circuit 41 can be reduced.
　実施の形態２に係るスイッチ１００では、突入時にはバイパス抵抗９２を経由するため、電気抵抗が１０Ωから１００Ω程度のバイパス抵抗９２を用いることにより、突入電流を定格電流と同等に抑制することができる。このため、実施の形態２に係るスイッチ１００は、リレー部などの部品サイズをアップさせることなく、電源入力線８１の接続先切替操作時に発生する突入電流を低減できる。 In the switch 100 according to the second embodiment, since the inrush current passes through the bypass resistor 92, by using the bypass resistor 92 with an electrical resistance of about 10Ω to 100Ω, the inrush current can be suppressed to the same level as the rated current. Therefore, the switch 100 according to the second embodiment can reduce the rush current that occurs when switching the connection destination of the power input line 81 without increasing the size of components such as the relay section.
　次に、上記の実施の形態１及び実施の形態２に係るスイッチ１００が備える制御部５のハードウェア構成について説明する。図１４は、実施の形態１及び実施の形態２に係るスイッチの制御部のハードウェア構成例を示す図である。図１４には、プログラムを実行するハードウェアを用いることによって制御部５の機能が実現される場合におけるハードウェア構成を示している。 Next, the hardware configuration of the control unit 5 included in the switch 100 according to the first and second embodiments described above will be described.

The processor 71 may be an arithmetic device, a microprocessor, a microcomputer, a CPU (Central Processing Unit), or a DSP (Digital Signal Processor).

The storage device 73 stores a program for executing the ventilation air volume determination process. The processor 71 reads the program stored in the storage device 73 into the memory 72 and executes it.
